Aluminium metal matrix nanocomposites (AMMNCs) have been recognized as a promising material with excellent structural and functional characteristics that can be suggestively personalized to satisfy industrial demands as well as design requirements for a wide range of applications, including those in defense, marine, automobiles, and aerospace. Particularly, these industries are using an increasing number of components manufactured by AMMNCs. When compared to monolithic materials, components manufactured from aluminium-based composites have better qualities such as tribological behaviors, hardness, stiffness, strength, and higher strength to weight ratio. Therefore, this article addresses the experimental investigation on aluminium-based metal matrix nanocomposites (MMNCs) with silicon carbide (SiC) and fly ash (FA) as a reinforcement material with distinct ratios. Here aluminium alloy 6061 and 7075, hereafter referred as AA6061 and AA7075, are considered as base material. The final workpieces obtained using the process of stir casting and machining are tested to compute the output response parameters like yield strength (YS), wear rate (WR), hardness, impact strength (IS), and ultimate tensile strength (UTS). In addition, the scanning electron microscopy (SEM) images also studied for examining the distribution of reinforcement material particles in base metal.

Machinability of hybrid metal matrix composite is quite difficult because of an anisotropic nature, abrasive effect, and nonhomogeneous arrangement of two (or more) hard reinforcements, which are infused in an unreinforced base alloy. Therefore, this paper proposes an experimental probe on machining attributes of the novel green hybrid metal matrix composite which is prepared by an advanced vacuum-sealed bottom pouring stir casting technique with Al7075-T6 as a base matrix and SiC/crumb rubber/MoS2 as three distinct reinforcements. The variable input parameters such as SiC content (3.5 and 4.5 wt.%), crumb rubber content (0.3, 0.6, and 0.9 wt.%), MoS2 content (3.5, 4.5, and 5.5 wt.%), stirring speed (580, 600 and 620 rpm), stirring time (2, 5 and 8 minutes), and pouring temperature (670, 700, and 730°C) are selected for the fabrication of hybrid composites via Taguchi L18 mixed-level orthogonal array. For the machinability of fabricated composites in terms of material removing rate and surface roughness under dry conditions, a conventional turning operation on a lathe machine was opted for fixed input parameters such as spindle speed (200 rpm), depth of cut (1.0 mm), feed rate (0.25 mm/rev), and machining time (30 seconds). In contrast to an unreinforced base alloy, the material removing rate of the proposed green hybrid composite is slightly increased by 1.47%, whereas surface roughness is significantly decreased by 12.14%. Further, these experimental outcomes are validated with the model created using an artificial neural network, which is based on Levenberg–Marquardt algorithm. Besides, the predicted values obtained from the artificial neural network model lie in the close vicinity of the experimental outcomes, which in turn ensure the authentication of the developed artificial neural network model for the machined aluminum-based green hybrid composites.

“…AA7075 exhibits good mechanical strength, corrosion resistance, fatigue strength and creep resistance compared to pure aluminium among all the aluminium series. It offers the highest strength and potential for dry sliding wear applications [20][21] [22]. Researchers reported the mechanical properties of various aluminium series, which indicates that AA7075 has the highest strength, hardness, and the lowest wear rate of all aluminium series, i.e., 1xxx, 2xxx, 3xxx, 6xxx, and 7xxx [23].…”

In this study AA7075/SiC/TiB2 closed-cell Aluminium hybrid composite foam (AHCFs) with different densities was fabricated by top-loaded bottom pouring stir casting technique. This technique uses oyster-shell powders (CaCO3 2.5 wt. % of composite with 60 μm size) as blowing agents and no viscosity-enhancing ingredient. The silicon carbide (SiC 0, 3, 6, 9, and 12 wt. % with 25 μm) and titanium di-boride (TiB2 3 wt. % with particle size 15 μm) are used as primary and secondary reinforcement agents. It has been noted that the addition of TiB2 and SiC enhanced the mechanical properties (modulus of elasticity, yield strength, and plateau strength) of AHCFs. The energy absorption capacity of AHCFs increases with the addition of SiC up to 3 wt. % and a further increase in SiC content leads to the reduction. It is observed that density and cell wall thickness increases with increasing the wt. % of SiC and Cell size and porosity decrease with an increase in wt. %. of reinforcement. It is also noted that Stirring temperature also strongly influenced the microstructural properties of AHCFs, and 750 0 C of stirring temperature is sufficient for aluminium foaming.
